Enhanced Marine Drop

When you have enough minerals, build 3-4 Barracks. When those are done, tech all the way up until DropShips are available. Start pumping out marines and DropShips. Get atleast 15 DropShips filled in with 8 marines in each. (Of course provide your own defense always) Also if you want you can fill your DropShips with 6 marines and 2 medics. Build another force of about 6-7 DropShips. Take those empty DropShips and enter them into the enemy base. The enemy might think that you are about to do a Unit Drop on him, then with your Dropships with the marines(and medics if you want) inside, enter the enemy base on a weak open spot. If the enemy base has air defense, then build battle cruisers and/or wraiths to take out the air defense before going in with your dropships. Try to drop all your marines(and medics if you chose them also) in the center of the enemy base. Backup your dropships with cloaked wraiths and/or battle cruisers. When you drop your marines, try getting your dropships back to your base and pump out more marines and/or medics for the same drop again. The faster you do all this the better. This strategy has been confirmed by all of my friends and IT DOES WORK if you do it correctly. Good Luck and have fun playing StarCraft and deafeting your foes.

CreepColony's Opinion: You should throw in some medics and detectors, and definetely stimpack your marines.
